title: Nutritional clinical studies in dermatology.
abstract: OBJECTIVE
  Nutrition has long been associated with skin health, beauty, integrity and aging through multiple pathways and cofactors implicated in skin biology. The onset and clinical course of various common skin diseases, especially acne, psoriasis, atopic dermatitis, and hair loss, have been suggested to be critically affected by nutrition patterns and habits. The relationship between acne and diet, predominantly the role of high glycemic load diets and dairy consumption have recently gained increased interest. Abnormal nutritional conditions such as obesity or malnutrition often manifest themselves by specific cutaneous features and altered skin function. Skin photoprotection, rendered by various nutrients, is well documented and appropriate nutritional supplementation has been shown to exert beneficial effects upon impaired skin integrity, restore its appearance and promote skin health. It is our intention to provide a comprehensive review of the most recent information on the role of nutrition for common skin diseases and regulation of skin biology.
  
  
  METHODS
  Nutritional clinical studies in dermatology have been reviewed using the MedLine literature source and the terms "diet" or "nutrition" and "skin".
  
  
  CONCLUSIONS
  The data on the relationship between nutrition and skin are until now controversial and much more work is needed to be done to clarify possible etiological correlations.
